A new 6(5).8 topology and a distorted 6(5).8 CdSO4 topology: two new supramolecular isomers of [M-2(bdc)(2)(L)(2)](n) coordination polymers

We report the crystal structures of two new coordination polymers that have similar composition but, despite having the same circuit symbol and Schlafli notation, different topologies: a novel 3D topology (USF-1) and a CdSO4-like topology.
